Answer:
1. B
2. A
3. B
Step-by-step explanation:
1. Can be checked using the vertical line test. By placing a vertical line at any x value, there can only be one point at which the line meets a part of the graph.
2. An x value can only correspond to one y value. B is incorrect since the x value of 5 is both -4 and 1 for the y values.
3. Same as above but with x and y charts. A x value can only correspond to one y value. A is incorrect as two of the same x values (2) appears and corresponds to two different y values (5 and 6).
